What is heat of vaporization for dummies?
The heat of vaporization is defined as the amount of heat needed to turn 1g of a liquid into a vapor, without a rise in the temperature of the liquid.
What is heat of vaporization in physics?
noun Physics. the heat absorbed per unit mass of a given material at its boiling point that completely converts the material to a gas at the same temperature: equal to the heat of condensation.
What is C in Clausius Clapeyron equation?
Representation of the Clausius–Clapeyron equation (p = pressure of the phase; T = absolute temperature; ΔH = molar enthalpy of the phase transition; ΔV = difference in the molar volumes of the two phases 1 and 2; c = integration constant; R = gas constant).
What is heat of vaporization in chemistry?
energy transfer latent heat, also called the heat of vaporization, is the amount of energy necessary to change a liquid to a vapour at constant temperature and pressure. The energy required to melt a solid to a liquid is called the heat of fusion, and the heat of sublimation is the energy…
How do intermolecular forces affect molar heat of vaporization?
The stronger the intermolecular forces, the higher the heat of vaporization. What happens to the evaporation rate as the intermolecular forces increase? The stronger the intermolecular forces, the lower the evaporation rate.
How to calculate heat of vaporization?
Measure the pressure inside a sealed vessel containing a volatile liquid over a range of temperatures.
How do you calculate heat of vaporization?
dP/dT is a derivative of pressure with respect to temperature.
What is the formula for heat of vaporization?
Use the formula q = m·ΔH v in which q = heat energy, m = mass, and ΔH v = heat of vaporization. q = (25 g)x(2257 J/g) q = 56425 J Part II: q = m·ΔH f q = (25 g)x(540 cal/g) q = 13500 cal Answer
How to calculate vaporization?
Concept of the Heat of Vaporization. To condense the water vapor into its liquid phase,we need to remove the energy from the gas.
